Four or five times a day when it is cold outside, lots more just to play when it is nice. We have a fenced yard and as soon as it warms up, you will hear one of the three by the door--woof. They all race out to chase birds and squirrels. When I want them back in, I shake the "cookie tin" Rosie will wait for me to shake the tin before she will come (who trained who there?) then she runs as fast as she can. Each dog gets one piece of gravy flavor dog food when she comes in.
